Pa. credit union sues Target over data breach

A western Pennsylvania credit union has sued Target Corp. for the credit union's cost of reissuing debit cards to about 75 customers whose account information was compromised by computer hackers who stole 40 million credit and debit card numbers from Target customers.

The federal lawsuit filed by the First Choice Federal Credit Union in New Castle seeks class action status, claiming there will be far in excess of the 100 victims and $5 million in aggregate damages once other financial institutions come forward.

The lawsuit doesn't say how much the credit union has spent to reissue its customer cards and take related precautions.

A Target spokeswoman repeated the Minnesota-based chain's assurances that customers aren't liable for any fraudulent purchases. She says the reimbursement process will be handled privately between Target and the affected banks.
